DISK-HIARROW.

SPECIFICATION forming part of Letters Patent No, 297,666, dated April 29, 1884.

Application filed June 22, 1883. (No model.)

To all whom it may concern:

Be it known that I, FRANK BRAMER, of Little Falls, in the county of Herkimer and State of New York, haveinvented certain new and useful Improvements'in Disk-'Harrows, of which the following is a specification.

My invention consists in certain improvements in harrows of the' character shown in Letters Patent No. 247,476, granted September 27,1881, to myself and George G. Crowley. In that patent is illustrated a machine in which, in order to insure a uniform depth of cut of the disks in each gang, the forward joint or connection of each gang with the draft-pole is lower than its rear joint. In the machine herein described and claimed, the front and rear joints of each gang-frame are arranged as just described. My present invention, however, consists in certain improvements in the connection of the draft-bars of the gangframes with the draft-pole or tongue,-so that the diskgangs may assume a position at right angles to the draft, and bring the planes of the cutting-disks parallel with the line of draft when the machine is backed, but may be held to work at any desired angle when the machine is moving forward.

In the accompanying drawings, Figure 1 is a plan View; Fig. 2, a side view of so much of a machine as is necessary to illustrate the invention; and Fig. 3 is a detail inverted view of a section of the tongue and the adj ustingplates.

The gang-frames A and B are hinged to the draft-pole or tongue of the machine at or about its rear endone of the fram es Abeing hinged to the side of the pole, and the other, B, at the end of the pole,somewhat in rear of the first. The end of the pole where the gang-frame B is secured is preferably reduced or cut away, as indicated in the drawings. The two gangs are braced and held stiff against vertical movement by'a bar, 0, one end of which is seated in a socket, a, on the gang-frame A, the bar being preferably held near its other end by the bolt 12, which connects the gang-frame B with the rear of the tongue. This construc- -tion permits the gang-frames to swing horizontally to vary the angles of the disks relatively to the line of draft, but holds the frames against independent vertical movement. The

each other.

held at suitable distancesapart by spacingthimbles in the ordinary way. At or about the middle of the gang-frames A andB draftbars E are secured and extend forward, preferably inclining toward the tongue of the machine, and are hinged or pivoted in the outer ends of pivoted rocking adjusting bars or plates F, carried on the tongue. A saddle or plate is bolted to the under side of the tongue, and has two wings or plates, G, which project laterally from the tongue and incline downwardly. The adjusting-plates F are pivoted at f in the outer ends of the wings G, and their inner ends are provided with cogs or racks formed in the arc of a circle and geared with The plates F are also provided with curved slots near. their inner ends, in which an adjusting stop-pin, Z, which passes through apertures in the plates or wings G, works. The ends of the plates F, gearing with each other, necessarily move together. On one of the wings (marked G) apermanent stop, m, is secured, and works in the slot in the adj usting'plate on that side, so that when the machine is backed the disk will be held in a position parallel with the line of draft, Fig. 3,

as illustrated by dotted lines in Fig. 1. An

aperture or pin-hole, n, is formednear the opposite side of this wing, so that "a pin inserted therein will be in the opposite end of the slot in the adjustingplate, and will prevent the gang-frames from swinging, and still hold the disks parallel with the line of draft when the machine is being drawn or transported from place to place, Fig. 3. In the opposite wing, G, pin-holes or apertureso are formed for the reception of the stop-pin or A pin inserted in either of these holes will hold the gang-frames at a given andetent Z.

gle as the machine is drawn forward when at work. When the pin 1 is inserted through the rear hole, 0, and through the slot in the plate, the end of the slot draws up against the pin and the gangs can swing back but a short distance. When the pin is in the forward hole, the adjusting-plates F swing farther back and let the gang-frames assume a greater angle to the line of the draft, and when the pin is removed and the plates F are allowed to swing until stopped by the permanent stop m, as in Fig. 1, the gangs will assume a still greater angle to the line of draft. Vhen the gangs are in this position,they may be locked by dropping the pin Z in the hole a. The stop on may, if desired, be movable.

I have shown two apertures only; but a greater number may of course be provided, so that the disk-gangs may be held to work at a greater number of angles.

It will be seen from the drawings, as above remarked, that as the adj listing-plates project outwardly and downwardly from the tongue the forward hinge-connections of the draftbars E are lower than the hinge-connections of the gang-frame with the pole, so that a uniform cut of the disks is insured.

I claim as my invention- 1. The combination, substantially as set forth, of the gang-frames, the draft-bars, the pivoted geared slotted adjusting-plates, the projecting wings or plates in which they are pivoted, and a pin or stop for limiting the swing of the gangs.

2. The combination, substantially as set forth, of the pole, the disk-gang frames hinged thereto, the draft-bars, the pivoted adjustingplates to which the draft-bars are hinged, and mechanism for controlling the movement of the plates so as to permit the disks to automatically assume a position parallel with the line of draft when the machine is hacked, and to hold the gangs at the desired angle when the machine is drawn forward.

3. The combination, substantially as set forth, of the draft-pole, the disk-gang frames hinged thereto at their inner ends, the draftbars, the pivoted adjusting-plates, which permit the disks automatically to assume a position parallel with the line of draft when the machine is backed, and hold the gangs at the desired angle when the machine moves forward, mechanism for limiting the movements of the adjusting-plates, and the hinge-connections between the draft-bars and adjustingplates, placed on a lower plane than the hingeconnections between the gang-frames anddraftpole.

4. The combination, substantially as set forth, of the pivoted geared adjusting-plates, the gang frames, connections between the gang-frames and the plates, and mechanism for controlling the movement of the adjusting-plates so as to vary the angle of the gangs.

5. The combination, substantially as set forth, of the draft-pole, the plate bolted thereon and having the laterally-projecting wings, the geared slotted adjusting-plates with which the gang-frames are connected,pivoted in said wings, stop-pin apertures in the wings, and a pin or detent for limiting the movement of the gangs.

In testimony whereof I have hereunto subscribed my name this th (lay of June, A. l). 1883.

FRANK BR-AMER.
